`App1ication filed November 21, 1921,. Serial No. 516,847.

To @ZZ 107mm it may conce/m Be it known that l, WILLIAM J. DECKER,

a citizen of the United States, and residing at In the construction of wooden frames for the windows of motor vehicle tops and for pictures and nirrors, it is customary to mortice the ends of the side and end frame members or to connect such members by means of splice pieces, glue being employed to assist in uniting these parts. `But in every case the parts joined are cut away in part, and irrespective of the perfection of the joint, it is usually the weakest part` of the frame. n substantially every case, a portion at least of the wood from which the frame members are made is seriously reduced in area and a portion of the wood is cross-grained at the joints. The glue disintegrates with age, especially when exposed to the weather, and the frame is weakened to that extent. y

The present invention consists of a sheet metal elbow whose cross section corresponds to that of the two parts of the frame united thereby and which is so rigidly folded around the edges of the frame members that the frame becomes stronger at the corners than at any other part.

t may be embodied in the structure shown in the drawing, wherein Fig. il is a front elevation of a. corner of a frame; Fig. Q is a rear elevation of the'top of a and Fig. 3 is a section on the line 3-3 vof Fig, l.

Similar reference characters refer to like parts throughout the several views.

The frame members l, 2 and 3 shown in the drawing are nearly half round in cross section and are provided with the rabbe'ts Il along their inner edges, extending along their entire lengths, to receive the sheet of glass, celluloid vor other transparent material. rPhe ends are rounded and preferably slightly reduced so that when the sheet metal corner members 5 are fitted around adjacent ends the surfaces of these metal members will be iush with the surface of the wood members. The side edges 6 and 7 of these corner members are then bent down to firmlyl compress the edges of the wood members, preferably sufiiciently lto sink these edges into the wood to produce continuous flatsurfaces, especially at the rabbets t.

The prime advantage of this construction is the. strength of the frame, but another advantage lies inthe ease with which the parts may be assembled,` finely fitted joints being unnecessary. 1n the drawing I have shown that the side and end members need not touch. A further advantage lies in the rabbets i of the several parts extending` their length so ythat it-r is unnecessary to round the corners of the sheets of glass to be mounted in the fra-mes.` As the joint between the ends of theI sheet metal corner members and adjacent shoulders on the wood may be close, the whole structure may receive a smooth shell of enamel which may entirely hide the joints.

The sheet metal corners may be varied 'to conform to side and end members of many varieties of frames without departing from the spirit of my invention asset forth in the -following claim. I
